Some of these are quite good. The translation from Catullus (pedicabo ego vos et irrumabo) isn't. I tried quite hard, and very unsuccessfully, to make something of that poem a couple of years ago; it's probably impossible to translate, at least into modern English, because there really isn't that much emotional force to shouting "faggot" any more.
I've always been a fan of that Ammons poem:
Their Sex Life
On top of another.
-- A.R. Ammons
